In the substrate processing unit 6, the substrate transfer chamber 10 of each substrate transfer unit 5 and each of the substrate processing chambers 15 to 18, 20 to 23, 26-29 and 31-34 or between the substrate processing chambers 15-18, 20-23, 26-29 and 31-34, and the substrate processing chambers 15- 18, 20 to 23, 26 to 29, and 31 to 34, the substrates 2 are processed one by one.

The substrate processing apparatus 1 is constructed as described above and the substrate processing chambers 15 to 18, 20 to 23, and 26 of the substrate transfer unit 8 or the substrate processing unit 6 of the substrate transfer unit 5 29 and 31 to 34 or the substrate transport mechanisms 36 and 38 are connected to the control section 59 and stored in the recording medium 60 incorporated in the control section 59. [

The substrate transport mechanisms 36 and 38 are controlled as described below by a substrate processing program, and are adapted to transport a plurality of substrates 2 at the same time. In the following description, the operation of the first substrate transport mechanism 36 will be described, but the second substrate transport mechanism 38 operates in the same manner.

First, in the substrate processing program, five substrates 2 are transported from a single carrier 3 placed on the substrate carry-in carriage 4 to the substrate transfer carrier 11 by using the transport device 8. In this substrate processing program, the upper 10 pieces of the upper and lower substrate transfer bases 11 and 12 which can mount 20 substrates 2 are transferred from the substrate loading / unloading station 4 to the substrate processing unit 6 The substrate transporting carriage 4 is successively divided into five pieces on the upper side and five pieces on the lower side among the 10 pieces used for carrying in each of the substrate transfer bases 11 and 12 by using the transfer device 8, So that the substrate 2 is transported from the one carrier 3 placed on the substrate transfer table 11.

5A, the substrate transfer mechanism 36 is moved to the position immediately before the substrate transfer chamber 10 and placed on the uppermost and second stages of the substrate transfer table 11 And receives the two substrates 2 at the lower and lower stages of the substrate support 44 and 45, respectively.

At this time, unlike the substrate backplane 45 (carrying-only substrate backbone) 45, which is the substrate substrate backbone (the substrate for loading and unloading the substrate back and forth) 44 of the interruption, The substrate 2 is held in the inclined shape of the front and back in the substrate holding portion 57b at the time of the second-stage loading of the substrate holding portion 57a and the two rear substrate supporting bodies 53 at the first- A state shown by a dotted line in Fig. 4).

Subsequently, in the substrate processing program, as shown in FIG. 5B, the substrate transport mechanism 36 is moved to any one of the substrate processing chambers (for example, the first substrate processing chamber 15 The substrate is moved to the immediately preceding room position of the substrate processing chamber 15 and the height thereof is adjusted and one substrate 2 processed in the substrate processing chamber 15 is taken out of the substrate processing chamber 15 do.

Subsequently, in the substrate processing program, one substrate 2 held in the substrate supporting portion 44 of the substrate transport mechanism 36 is carried into the substrate processing chamber 15, as shown in Fig. 5C.

At this time, the abrupt substrate abutment region (transfer substrate support region) 44 moves back and forth by a long distance, unlike the substrate abutment region 45 (transfer substrate only), which will be described later The substrate holding portion 57a and the rear two substrate supporting bodies 53 are held in a sloped shape in the front and rear directions in the substrate holding portion 57b at the time of the second-stage loading of the two front substrate supporting bodies 53, (In a state shown by a dotted line in Fig. 4) is carried into the substrate processing chamber 15. As shown in Fig.

5D, the substrate transfer mechanism 36 is moved to another substrate processing chamber (for example, the second substrate processing chamber 16) while holding the two substrates 2, And one height of the substrate 2 after the processing in the substrate processing chamber 16 is taken out of the substrate processing chamber 16 to the abutting substrate backing 44. [

At this time, unlike the uppermost substrate support (transfer only substrate support) 43 (Fig. 5B) described above, the substrate support (interposed / , The substrate 2 is transported from the substrate holding portion 58b at the time of carrying out the first stage of the substrate holding portion 58a and the two rear substrate holding bodies 53 at the time of carrying out the second stage of the two front substrate supporting bodies 53 (In a state shown by a solid line in Fig. 4).

Subsequently, in the substrate processing program, one substrate 2 held by the substrate support 45 at the lowermost end of the substrate transport mechanism 36 is carried into the substrate processing chamber 16, as shown in Fig. 5E.

5F, the substrate transfer mechanism 36 is moved to the position immediately before the substrate transfer chamber 10, and the substrate transfer is carried out simultaneously at the uppermost stage and the interrupted substrate stages 43, 44 at the same time The two substrates 2 to be held are transferred to the third stage and the lower stage of the substrate transfer platform 11, respectively.

At this time, the abrupt substrate abutment region (transfer substrate support region) 44 is moved forward and backward by a short distance different from the uppermost substrate abutment region (transfer only substrate abutment region) 43, The substrate 2 is held by the substrate holding portion 58b at the first stage of the substrate holding portion 58a and the two rear substrate holding bodies 53 at the time of carrying out the second stage of the substrate holding portion 53, (The state shown by the solid line in Fig. 4).

Thereafter, in the substrate processing program, the five substrates 2 are transferred to any one of the carriers 3 placed on the substrate transfer platform 4 from the substrate transfer platform 11 using the transfer device 8 . In this substrate processing program, the lower 10 pieces of the upper and lower substrate transfer bases 11 and 12 which can mount 20 substrates 2 are transferred from the substrate processing unit 6 to the substrate loading / unloading station 4 And the upper side and the lower side of the 10 pieces used for carrying out the respective substrate transfer bases 11 and 12 are divided into 5 pieces and the lower side are sequentially transferred from the substrate transfer table 11 to the substrate And the substrate 2 is carried to any one of the carriers 3 placed on the platform 4.

In the above description, a case has been described in which the two substrates 2 are simultaneously conveyed while being held by the substrate conveying mechanism 36 having the three substrate supporting portions 43, 44 and 45. However, Two or more (N-1 or less) substrates 2 can be simultaneously held and transported by using a substrate transport mechanism having three or more substrates.

As described above, in the substrate processing method using the substrate processing program in the substrate processing apparatus 1, three substrate buffers 43, 44, and 45 for holding the substrates 2 one by one are provided In the case where the substrate 2 is transported to the substrate processing chambers 15 and 16 by using the substrate transport mechanism 36 and the substrates 2 are processed one by one in the substrate processing chambers 15 and 16, Two substrates 2 are simultaneously held by the respective substrates 1 to 43, 44 and 45 and the substrates 2 are transported one by one to the substrate processing chambers 15 and 16, Can be shortened and the throughput of the substrate processing can be improved.

The number of the substrate posts 43, 44, 45 is not limited to three, but may be N (N is an integer of 3 or more), and 2 to N-1 substrates 2 may be simultaneously conveyed It is possible to shorten the time required for conveyance of the substrate 2 further by conveying the N-1 pieces of the substrates 2 at the same time, and it is possible to improve the throughput of the substrate processing. Further, when all the N substrates are simultaneously transported, the substrate 2 processed by the substrate processing chambers 15 to 18, 20 to 23, 26 to 29, and 31 to 34 can not be taken out, 2 can not be carried out at the same time and must be transported by the carrying-in and carrying-out of the substrate 2, and the time required for transporting the substrate 2 becomes longer.

Particularly, in the substrate conveying mechanism 36 of the above-described substrate processing apparatus 1, one of the plurality of (here, three) substrate supporting portions 43, 44, The substrate 2 is transferred only by carrying the substrate 2 to the substrate processing chamber 15 and the other substrate holding portion 43 is transferred only from the substrate processing chamber 16 to the substrate processing chamber 16, 44 are used to carry the substrate 2 into the substrate processing chamber 15 and to transport the substrate 2 from the substrate processing chamber 16, It is possible to simplify the structure of the substrate transport mechanism 36 and to improve the assembling workability or the maintenance property of the substrate transport mechanism 36, Can be reduced.

A plurality of (three in this case) substrate supports 43, 44 and 45 are arranged vertically in the substrate transport mechanism 36 of the substrate processing apparatus 1, The substrate 2 before being processed in the substrate processing chamber 15 is placed on the uppermost substrate support 43 so that the substrate 2 can be removed from the substrate processing chamber 15, It is possible to prevent particles and the like adhering to the substrate 2 before processing from dropping and damaging the substrate 2 held by the lower substrate supports 44 and 45. [

The substrate transfer mechanism 36 of the substrate processing apparatus 1 includes a plurality of (three in this case) substrate bores 43, 44 (44, 45) arranged vertically and arranged vertically The substrate 2 is carried into the substrate processing chamber 15 (16) by one of the two substrate supporting portions 44 (45) provided in parallel with the substrate supporting portion 44 (45) Since the substrate 2 is to be taken out from the substrate processing chamber 15 (16) with the substrate transfer mechanism (44), the distance for moving the substrate transfer mechanism (36) is shortened, and the transfer time can be further shortened. While the substrate 2 is carried out from the substrate processing chamber 15 (16) by the other substrate holding region 43 (44), the one substrate holding region 44 (45) 16), the opening area of the substrate processing chamber 15 (16) is made smaller when both substrates are simultaneously present in the substrate processing chamber 15 (16) And the size of the substrate processing chamber 15 (16) can be reduced.

In the substrate processing apparatus 1, a carrier 3 mounted on the substrate carry-in carriage 4 and a substrate transfer carrier 11, The number of N (in this case, three) or more (here, five) substrates 2 are collectively transported, so that the time required for transporting the substrate 2 can be further shortened, The throughput of the substrate processing can be improved.
